TI-83 silver is inferior to the TI-89.
I think his point is that the TI line has remained the same for a very long time. FWIW, the TI-89 Ti has been in existence for at least 5-6 years.
Still, due to the generally high prices I'd say this is a good deal for a new TI-89 Titanium.
When I took calculus in highschool we were allow calculators on the tests, so I just used the notepad on my ti 84 to hold a bunch of equations basically I really didn't need to know anything. I can see why teachers don't allow them on tests.we aren't allowed to use Ti-89 on tests do to cheating concerns (homework is fine) I think that is just silly!
Sad when you can buy an iPhone app that does so much more for $4 (Graphing Calculator, must have for Math and Engineering students) and the same thing for $20 (Rk-89, emulated Ti-89 or Rk-84 for $4) and can't use them in class. I own a Ti-84 Plus for class, we aren't allowed to use Ti-89 on tests do to cheating concerns (homework is fine) I think that is just silly!
I also have a basic Ti-30 (should of gotten the solar one), cause its just damn sexy.
I saw basically the same thing advertised in the frys ad a few weeks back for the back-to-school period. Pretty much everything mentioned above is what was going on thu my head at the time. I still have my TI 89 from about 15 years ago which also cost about the same.
How much do you think a working Chinese rip off of these things could be made for? 5$?
I bought mine used off ebay (locally) for ~$60-70 I think...
Was quite handy in Linear Algebra, but now we're in Calc I and II and we're back to a TI-30 because the 89 can do "too much" ... haha..
I bought my TI-89 in 2000 back in high school. That was after my sister lost my TI-86. Definitely liked the 86 better.
